BLADE-HOLDER 0F SAFETY-RAZORS.

Bpeoication of Letters Patent.

Patented Feb. 1 7,1914.

Toall 'whom it may concern Be it known that I, VILLIAM JAMES MY- .\'rr, a subject of His Majesty the King of England, and residing at Birmingham, in England, have invented new and useful mproveinents in or Relating to Blade-Holders of Safety-Razors, of which the following is a specification.

This invention comprises certain improvements in or relating to blade holders, for safety razor blades, of the type comprising upper and lower jaws adapted to receive the rear portion of the blade, and it has for lts object a holder which better facilitates the positioning and detachable securing of the blade within the holder than heretofore.

To these ends theainvention consists in the constructions and combinations of parts such as will be hereinafter described-and ointed out in the claims which conclude this descript-ion. n

In the accompanying drawin s: Figures 1 and 2 are respectively side an front elevations of the upper art of a safety razor provided with a bla e holder` constructed according to the invention. F1 3 is a view of a blade holder having a b ade secured therein. Fig. .4 is a view of the blade holder illustrated in Fig. 3, showing the blade dremoved therefrom, and the lookin v parts out of the engaging position. i 5 is a transverse section on line w :v o Fig. 3. Fig. G is a longitudinal section on line y y of Fig. 3. Fi 7 is a longitudinal section on line y 1/1 o Fig. 4. Fig. 8 is a sectional plan, the section being taken on line z z of Fig. 7.

Referring to Fi s. 1 to 8 inclusive the holder 1 is forme from sheet metal bent upon itself and around the hinge in 1 and n pin 2 is rotatably fitted at eac side of the holder, the portion 3 of such pin which extends between the jaws being notched as at 9 to a depth conveniently equal to half the diameter of the pin. One end of the pin 2 is provided with a cup head 4. which abuts against the underside of the lower jaw 5, and at its other end is provided with any suitable means to facilitate the rotation of the pin. Such means may consist of a lever comprising a disk having an outwardly projecting arm 6, and having a yrectangular aperture 7 to tit over the correin 2 which s ondmg sha ed end of the p p ai@ disk in end is thenl riveted over to hol position upon such in and againstthe upper jaw 8 of the holt er. To fix the blade in position the notched pins 2 are turned by means of the rojecting arms 6 so that the notches 9 are disposed on the inside and adjacent one another as shown by Fig. 4 there- )y allowing the blade l0 to pass therebetween. Tlie blade is then pushed between the jaws 5 and 8 of the holder whereupon the side notches 11 of the blade reaister with the notches 9 in the pin, the pins being then rotated through 180 so that the unnotched part of the pin engages in the notches 11 of the blade 10 to thus prevent. the removal of the blade. The pins 2 preferably engage with the rear sides of the blade notches 11 to hold the blade against the back of the holder to thereby prevent any looseness of fitting. The thumb lever thus provides very convenient and compact means for rotating the notched pins, as to rotate such pins, the thumb may be merely placed on the lever and pressed downwardly and outwardly. The thumb levers are prevented by their frictional engagement wit-h the surface of the holder from being inadvertently rotated, the inherent resiliency of the folded sheet metal holder or the lever causing such lever and holder to be pressed together. This feature is specially advantageous in the case of a holder retaining the blade while being stropped, as during the stropping the levers are liable to frictionally engage with the sti'o and be rot-ated and thus allow the hol er to release the blade. This resiliency of the holder also enables the jaws to obtain a better grip upon the blade as when the thumb levers are closed the pressure of the same on the jaws tends to close said jaws upon the blade.

Having thus described my invention what I claim as new and desire to secure by Letters. Patent of the United States of America is 1. A pivotally mounted blade holder comprising up er and lower jaws between which the blade is placed from the front thereof, and locking and positioning means adapted to enga e with side notches in the razor blade, w ich lookin and positioning means com rise a rotatab y mounted pin extending etween the jaws and adapted to be rotated to be moved out of and into engagement with a side notch in the blade, and thumb operated means attached to said pin which -rictionally engages with the surface of .a

jaw of the holder to prevent accidental rotation of the same.

z2. A pivotally mounted blade holder cornprising upper and lower jaws between which the blade is placed from the front thereof, and locking and positioning means adapted to engage with side notches in the razor blade, which locking and positioning means comprise a rotatably mounted notched in extending between the jaws and ada-pte to be rotated to be moved out of and into engagement with a side notch the blade, and thumb operated means attached to said pin which engages with the surface of a jaw of the holder to prevent accidental rotation of the same.

3. A pivotally mounted blade holder comprising upper and lower jaws between which jaws the bladeis placed from the front thereof, and lockingand positioning means arranged at each side of the holder and adapted to engage with side notches in the razor blade, which locking andpositioning means comprise rotatably mounted pins extending between the jaws and adapted to berotated to be moved out of and into engagement with the side notches in the blade, and thumb operated means attached to said pins 'which rictionally engage with the surface of a jaw ofthe holder to prevent accidental rotation of the-same.

each side of the holder and adapted to en,

gage with side` notches in the razor blade,

which locking 'andposit-ioning means comprise rotatably inounted pins extending be# tween the jaws and adapted to be rotated to be moved out of and into engagement with the side notches inthe blade, and thumb operated means attached to said pins which engage with the vsurface .of a jaw of vthe holder to prevent 'accidental rotation of the same.

5. A rotatably mounted bladeA holderfor' safety razors comprising a hinge pin, upper and lower jaws formed by bending a sheet metal blank upon itself and around such hinge pin, and locking means, adapted to engage with side notches in the razor blade,

comprising rotatably mounted pins on each side of the holder, said pins being notched and having levers for rotating the same whichlevers when in the locking position lie on the underside .of the lower jaw.
